How can I enable remote debugging for SBT in windows?

Question

I would like to accomplish running the equivalent of this

sbt -jvm-debug 5005

However I don\'t seem to be able to pass in args in Windows.

Answer 1

set SBT_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005
sbt run

was the only working solution on Windows 7.

Answer 2

Currently, I'd downloaded the last updated sbt, exactly sbt 1.3.3 but when I want to enable debug in the project, I had the same problem as you. Investigating, I could see that I haven't this file (sbt-launch-lib.bash) in my own root C:\Program Files (x86)\sbt\bin so when I see in another machine, I could notice that sbt, It was 1.2.8 and yes it had the file that I mentioned before so I uninstalled sbt 1.3.3 and I installed sbt 1.2.8 and put in my project sbt -jvm-debug 9999 and it works.

Answer 3

Seems like the Windows version of SBT doesn't define this functionality.

On Linux it is defined in the $SBT_HOME/sbt/bin/sbt-launch-lib.bash as

addDebugger () {   
  addJava "-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=$1" 
}

You can achieve the same result by setting the SBT_OPTS environmental variable on Windows.

Run SBT like this, to make the debugger listen on port 5005

set SBT_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005" && sbt
